What is your favorite flint? I like TC Premium Agates. Not the TC standard flint. Does anyone think there are better flints?
Probably for example English or French amber, etc.
Specifically for TC flintlocks.
I have found a way to improve TC spark/lock time. Get the thinnest leather possible for a main wrap. Put a thicker piece of leather between the bottom jaw and the bottom of the thin leather wrapped around the flint. Just a piece underneath, not wrapped around .... this raises the flint so you can strike a lot more than just half the frizzen.
Years ago I tried the suggestion of using a flattened lead ball instead of leather. I found that I broke flints very easily with this method.
Black English flints. Easily re=sharpened by knapping. You can't knap an agate flint. On TC locks, it's not that English flints are too hard, but TC frizzens (older ones anyway) are too soft. When I had a TC flinter, it improved a lot when I had the frizzen re-hardened.
